The document discusses various basic hand tools used in electronics servicing. It describes screwdrivers like slotted and Phillips screwdrivers. Soldering tools discussed include soldering irons, soldering tool stands, and desoldering tools. Boring tools mentioned are mini-drills and portable electric drills. Cutting tools include utility knives and hacksaws. Auxiliary tools discussed are magnifying glasses and paint brushes. Electrical equipment defined are volt-ohm-milliammeters, oscilloscopes, and signal generators. The document concludes by asking the reader to classify different hand tools according to their specification.

2. SCREWDRIVERS
are hand tools specifically designed to insert
and tighten, or to loosen and remove
screws.
Types of Screwdrivers

3. TYPES OF SCREWDRIVERS

4. SLOTTED SCREWDRIVER
 is used to drive or fasten negative slotted
screws.

5. PHILLIPS SCREWDRIVER
is used to drive or fasten positive slotted
screws. It is a screwdriver that could take
greater torque and could provide tighter
fastenings.

6. JEWELER'S SCREWDRIVER SET
is a set of small screw drivers composed of
slotted and Phillips screwdrivers.

7. SOLDERING TOOLS

8. SOLDERING IRON
is a device for applying heat to melt solder in
attaching two metal parts. A soldering iron is
composed of a heated metal tip and an
insulated handle. For electrical work, wires
are usually soldered to printed circuit boards,
other wires, or small terminals. A low-power
iron (20-30 Watts) is suitable for this work.

9. SOLDERING TOOL STAND
is a place where the soldering iron is placed
during usage. This will keep the soldering
iron away from flammable materials. The
stand often comes with a sponge used in
cleaning the tip of the soldering iron.

10. DESOLDERING TOOL
is used in removing soldered wires and
components on printed circuit boards for
troubleshooting and repair purposes.

11. SPLICING TOOLS

12. LONG NOSE
is used for holding, bending, and stretching
the lead of electronic component or
connecting wires.

13. SIDE CUTTER
is a wire-cutting pliers, though they are not
used to grab or turn anything, but are used
to cut wires.

14. WIRE STRIPPER
is a pair of opposing blades much like
scissors or wire cutters. The addition of a
center notch makes it easier to cut the
insulation without cutting the wire.

15. BORING TOOLS

16. 12V MINI-DRILL
is used to bore or drill holes in the printed
circuit board (PCB) with sizes from 1/32” –
1/16”.

17. PORTABLE ELECTRIC DRILL
is used for boring hole(s) in plastic or metal
chassis with the use of drill bits having
sizes from 1/6” to approximately 1/4”.

18. METAL FILES
These are hand tools having a series of sharp, parallel
ridges or teeth. Most files have a narrow, pointed
tang at one end to which a handle can be fitted.
Flat File is
parallel in
width and
tapered in
thickness;
they are
used for
flat
surfaces
and edges.
Half Round
File is
tapered in
width and
thickness,
coming to
a point,
and
is narrower
than a
standard
half round
and used
for filing
Round File - is
also called rat-
tail file which
is gradually
tapered and
used for many
tasks that
require a round
tool, such as
enlarging round
holes or cutting
a scalloped
edge.

19. CUTTING TOOLS

20. UTILITY KNIFE
is a common tool used in cutting various
trades and crafts for a variety of purposes.

21. HACKSAW
is used for cutting metals. Some have pistol
grips which keep the hacksaw firm and
easy to grip. The small hand-held
hacksaws consist of a metal arch with a
handle that fits around a narrow, rigid
blade.

22. AUXILIARY TOOLS

23. MAGNIFYING GLASS
is a convex lens which is used to produce a
magnified image of an object. The lens is usually
mounted on a frame with a handle. Roger Bacon
is the original inventor of the magnifying glass. A
magnifying glass works by creating a magnified
virtual image of an object behind the lens. Some
magnifying glasses are foldable with built-in
light.

24. PAINT BRUSH
is a type of brush made of bristles set in
handle, used for cleaning dirty parts of a
circuit or an object aside from using it for
painting.

25. ELECTRONIC EQUIPMENT

26. VOLT-OHM-MILLIAMMETER
It is an equipment that combines three
functions: as a voltmeter that measures both
ac and dc voltages; an ohmmeter that
measures resistance; and milliammeter that
measures small amount of dc current.a

27. OSCILLOSCOPE
An oscilloscope (commonly abbreviated CRO, for
cathode-ray oscilloscope, or scope) is a piece of
electronic test equipment that allows signal
voltages to be viewed, usually as a two
dimensional graph of one or more electrical
potential differences (vertical axis) plotted as a
function of time or of some other voltage
(horizontal axis).

28. SIGNAL GENERATOR
A signal generator is a device which
produces simple wave forms.
